Hello, I apologize for such a stupid question - but I just don’t get it. I am also new to this board and these systems, so my experience is extremely limited.
What I want to do:
- SiFive Freedom U740 SoC board is connected to another microcontroller board using LPC1768, through UART 0 (on both ends)
- The LPC1768 will transmit UART data to the U740 board
- The U740 receives the data, by an interrupt
- U740 executes based on what data was received from UART
I can confirm that the LPC1768 is sending the data correctly, but I cannot wrap my head around accomplishing on getting the U740 to trigger an interrupt when it receives the data.
I took a look at this sample code, but I do not know what changes are required to trigger an interrupt on Rx. It seems that this code triggers on Tx.
freedom-e-sdk/software/uart-interrupt/uart-interrupt.c at master · sifive/freedom-e-sdk · GitHub
Can someone please shed some light on this?
Thank you and have a wonderful holiday!
